Abstract :
A dedicated proton synchrotron for cancer therapy has been designed. It consists of a multicusp H- ion source, a tandem electrostatic accelerator as an injector, a slow-cycling synchroton, and beam lines to two treatment rooms. The synchrotron accelerates 5-MeV protons up to 230 MeV. The design goal with respect to its intensity is 10 nA for 0.5 Hz and 20 nA for 1 Hz repetition rate. Beam loss caused by Coulomb scattering in the ring and transmission in the tandem accelerator are estimated
